Question

我正在尝试运行以下代码并从另一个笔记本中调用一个函数，但我似乎无法弄清楚将所有图像数据加载到目录中的情况。

for index, row in dataset.iterrows():
    x.append(array(ela_form(row[1], 90).resize((128, 128))).flatten() / 255.0)
    y.append(row[0])

iam调用的功能是我导入的另一个笔记本中的ela_form。

def ela_form(path, quality):

    im_name = path
    rename_image = im_name.split('.')[0] + '.resaved.jpg'
    ELA_filename = im_name.split('.')[0] + '.ela.png'

    im = Image.open(im_name).convert('RGB')
    im.save(rename_image, 'JPEG', quality=quality)
    resaved_im = Image.open(rename_image)

    ela_image = ImageChops.difference(im, resaved_im)

    extrema = ela_image.getextrema()
    max_diff = max([ex[1] for ex in extrema])
    if max_diff == 0:
       max_diff = 1
   scale = 255.0 / max_diff

   ela_image = ImageEnhance.Brightness(ela_image).enhance(scale)

   return ela_image

我的图像存储在'dataset \ Training_Data_Preprocessed'

Dataset.csv存储在'dataset \ Dataset.csv

中
